FSH R, or follicle-stimulating hormone receptor, is a transmembrane G-protein coupled receptor that is expressed in the ovaries, uterus, and testes. The ligand for this receptor, considered to be the central hormone of mammalian reproduction, is called follicle stimulating hormone (FSH) [1]. In females, FSH R is essential for proper ovarian development and follicle maturation. In males, it is required for normal spermatogenesis.
